The presented article deals with the catchments of three streams, which are right-hand tributaries of the Černá Opava river, where new foresthydrology research activities of the Forestry and Game Management Research Institute and Czech Hydrometeorological Institute begun. The focus of the work in the years 2019–2021 was on field research and measurements, spatial analyses in GIS and mathematical modelling using rainfall-runoff and hydrodynamic models, thus we can mention HEC-HMS, SIMWE and MIKE SHE/11 models among others. The article provides an overview of current outputs from these activities. It also outlines the issues of the impact of land use, forest health including its extreme phases on hydrological conditions and the response of river basins to precipitation inputs. Besides that, the issue of variable contribution areas of the river basins and the possibilities of their research at the level of monitoring (e.g. measurement of fl ows and volumetric soil moisture) and mathematical modelling using complex fully distributed precipitation-runoff models are discussed as well. At the same time, basic hydrological characteristics of the studied catchments were provided. [ABSTRACT FROM AUTHOR]

Introduction: A considerable body of evidence has shown that the parental educational level (PEL) as well as health status in early childhood play a significant role in child dental caries. A multicentric European Longitudinal Study of Pregnancy and Childhood (ELSPAC) conducted also in Brno collected a great amount of data from clinical and socio-economic areas related to children's general health. Aim: To assess the relationship between caries experience and gingivitis manifestation in 13-years-olds to 15-years-olds and the PEL of their parents in a retrospective case-series study. Methods: Randomly selected children from an ELSPAC cohort in Brno (n = 780) were orally examined and their dental status (D3MFT [WHO criteria]) and gingivitis were recorded. Data on the PEL were retrieved from the ELSPAC database. Correlations between both DMFT and GI vs PEL were calculated using ANOVA and χ2-test. (Statistica v. 8.0., Statsoft Inc., Tulsa, USA.) Results: Mothers' (but not fathers') educational level significantly negatively correlated with D3MFT scores of children (p < 0.05). Similar correlation between GI and PEL was not found. Conclusion: The study confirmed a significant correlation of the educational level of mothers and caries experience in children (p < 0.05), while the correlation between GI and PEL was not significant.
